Less Than or Equal(<=) Comparison Operator in JavaScript

JavaScript Less Than or Equal(<=) to the operator is used to compare two operands and return true if the left operand is smaller or equal to the right operand. The algorithm used for the comparison is the same as that of less than operator but equal condition is also checked

Syntax:

a<=b

Example 1: In this example, we will compare String, Number, and Boolean using Less Than or Equal Operator.

Javascript

console.log("3"<=2);
console.log("2"<=3);
console.log(true<=false);
console.log("3"<="2");
console.log(3<=2);

Output: The values are converted to the same data type and then compared. Here true is treated as one and false as 0. Therefore false is less than true. 

false
true
false
false
false

Example 2: In this example, we will use the greater than or equal operator on BigInt and other data types.

Javascript

console.log(2n<=2);
console.log(5n<=4);
console.log(undefined<=null);
console.log(null<=undefined)

Output: 2n is equal to 2 as the comparison is made after type conversion

true
false
false
false
